X + 7 2x + 12
4) Which expression represents the area of the triangle?
A) 3x + 19
B) 3x2 + 84
x+ 13x + 42
D) 2x2 + 26x + 84

dude   i don't even know. i've been trying for hours.

step-by-step explanation:

2^y = ln 5, or   y(ln 2) = ln 5.   solving for y,   y = (ln 5) / (ln 2).   y=5

step-by-step explanation:

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !
